The 2-MIX Engine
You will notice right away that both the 271 and 291 models come equipped with the 2-MIX engine. This engine is not only more than powerful, but it offers a lot of high lugging power.
With the 271 models, users can expect 2.6 kW of power, while the 291 model offer right around 2.8 kW of pure power.
There is simply no denying that both models come equipped with a powerful motor, but do not let this fact deter you because it won’t burn through the fuel like one would think.
In fact, these 2-MIX engines were specifically designed with technology to help fuel consumption.
With this new innovative technology, owners can cut as must a 20 cents off fuel consumption when compared to other models and 50 cents compared to those models without with 2-MIX engine.
Pre-Separation Air Filter
If you have owned a chainsaw in the past then you know that they do not come without a ton of maintenance responsibilities.
Not only do you have to constantly keep an eye on the gas and bar oil, but you have to watch the filter.
If the filter gets clogged it will bog down the engine and prevent the machine from running as efficiently as possible, which will only reduce the life of the motor.
This is just another area where both the 271 and 291 excel. Both models come equipped with what is known as a pere-separation ait filtration system.
This system is so effective that it can take the traditional air filter and add five times its normal life span.
Getting 5 times the life out of your air filter will not only ensure that your chainsaw runs more efficiently during each use, but it could help you cut the costs of buying as many air filters.
Not to mention saving the time that it takes to change the air filter.
You can look at any Stihl chainsaw and see that it was really built to last. This is even more true with the 271 and 291 models.
Not only do they feature a rugged design with a high standard finish, but they come equipped with an anti-vibration system.
This anti-vibration system includes springs installed between the engine and the handle system. This system was specifically put in place to help reduce the vibrations that are generated by the engine as well as the moving chain.
Not only does this reduce the wear and tear on the machine, but it reduces the fatigue on the user as well.
Smooth cutting behavior and fewer vibrations ensure smoother cutting operations.
The Side-Access Chain Tensioner
It doesn’t matter what kind of chainsaw or buy or which manufacturer you buy, there are going to be times when you have to tighten the tension on the chain. This is just a regular part of owning a chainsaw.
Tightening the tension will not only help keep the blade sharper for longer periods of time, but it will ensure that the chain doesn’t get too stretched as well.
If you are familiar with the process, you probably already know that it isn’t all too hard and only takes a few seconds. Well, the Stihl 271 and 291 has made the process even easier.
Both models now offer what is known as the side-access tensioner. This tensioner makes it much easier and convenient for the user to adjust the chain with a bar wrench.
Both the Stihl MS291 and MS271 Farm Boss chainsaws are designed with a heavy-duty ergonomic handle. The design ensures comfort and less shock caused by the impact of vibration.
The rubberized material on the handle will reduce shock while offering better handling and full control, even when your hands are damp with sweat and moisture.
Both chainsaws are compatible with guide bars between 40 and 50 centimeters or 16 and 20 inches in length. Of course, Stihl recommends utilizing a guide bar from its Rollomatic series.
These guide bars are constructed of high-grade steel. So, they are guaranteed to last longer than most of the competitor brands.
If you are in the market for a new chainsaw, you simply can’t go wrong with the Stihl name. Stihl is without a doubt one of the most prolific chainsaw manufacturers on the planet and will continue to be so to the end of time.
Their innovative designed coupled with their integrity and dependability have propelled them into what they are today as a company.
However, sometimes as you can see just choosing the Stihl name isn’t enough. You have to choose a specific model that best suits your needs.
Both the 271 and 291 models have a lot to offer, but the one that you choose will really depend on the tasks that you plan on undertaking.
